WILLIAM L; ZPFEFFERKORN AND ALBERT P. SCI-ILOERB, 0F MILWAUKEE,WISCONSIN,

ASSIGNORS OF ONE-THIRD T0 AUGUST H. HAMIVIETTER, OF MILWAUKEE, WIS-cousn' To all whom it may concern.

Be it known that we, WILLIAM L. PrerrEnnoRN and ALBER P. SGI-ILOERB,citizens of the United States, residing at Milwaukee, county ofMilwaukee, and State of Wis cousin, have invented new and usefulImprovements in ExtensionTables, of which thefollo'wing is aspecification.

Our invention relates to improvements in extension .tables.

' The object of our invention is to provide means whereby the top of anextension table may be tilted in either the closed or extended positionto permit the table to pass through a door-way or to facilitate storingit at one side of a room in such a position that it will occupy minimumspace.

, In the drawings- Figure 1 is an end view ofan extension tableembodying our invention, showing the top in tilted position.

*ig. 2 is a plan view of thesame, showing the top in normal position.

I Fig. 3 is afragmentary sectional view, drawn to a plane cutting thehinge pintle transversely and showing a modified form of hinge withfragments of the cap board and tilted bridging board.

Fig. 4 is a view of the hinge shown in Fig.3 as seen from the underside, together with fragments of thecap board and bridging board.

Fig. 5 is a sectional view, drawn on. line mm of Fig. 2. a V

Like parts are identified by the same reference characters throughoutthe several views.

The drawings illustrate our invention as applied toa table of the typeknown as a pedestal extension table. The pedestal members A A, areprovided with supporting feet-A and with cap boards B. Bridging boards Cextend transversely of the table top and normally rest upon therespective cap boards B. Each bridging board is hinged to a pair ofguide bars D, D, mount edaupon one ofthe cap boards B, and the hingeconnections are so located that the central portion ofthe bridging boardmay restupon the cap board B, from which it is supported between theguide bars D, D. The bridging boards are recessed at C to permit themtopass between the guide bars. The hinges E are of ordinary type, withone leaf or ea h h ng sec red t we earl f a EXTENSION-TABLE.

Specification of Letters Patent. Patented Jan. T5, ll lllg. Applicationfiled November 20, 1915. Serial No. 62,522. i

guide bar D and the other leaf secured to the under surface of thebridging board C in such a position that the recessed portion of thebridging board will register with and receive the guide bars D, whensuch bridging board is in normal position. These hinges E, however,permit both bridging boards C, C, to be raised from their respective capboards B and supported from the bars D and hinges E in the tiltedposition shown in F ig. 1. T he pintles ofthe several hinges are inalinement and in aline which extends longitudinally of the table,parallel with, but offset laterally from, the central longitudinal lineof the table. a The tilting movement of the bridging boards is limitedby links F, F, which are pivotally connected with each other at f. Thelink F of each pair is connected with the cap board B by a pivot pin f.The other link F of each pair is secured to the corresponding bridgingboard by a pivot pin F, the bridging boards being provided withprojections C to receive the pivot pins f. i The link F may be providedwith a bracket stop G to limit the unfolding movement and thereby alsolimit the tilting movement of the bridging boards.

Extension slides H are mounted upon the bridging boards C in the usualmanner. These slides support the table top members I, as in all ordinaryextension tables. When the bridging boards are in normal position, theguide bars B are engaged in the recesses C of the bridging boards, sothat when the table top members I, I, are drawn outwardly or pushedinwardly, the pressure is transmitted through the slides to the bridglngboards and received by one or the other of the bars 13, therebyrelieving the hinges from strain. The hinges are sufiiciently loosejointed, or the boards C and bars B closely fitted, to allow thebridging boards D tobear upon the bars B without imposing strains uponthe hinges. r When the bridging boards are in normal position, the linksF, F will of course occupy the folded, position in which they areillustrated in Fig. "2. Eachof the brldging boards may be provided witha locking device, such as the turn button J, one end of which may engageunderneath one of the bars B at that end which is opposite the oneprovided with the hinge E. A When the button is in holding position, asindi cated by dotted lines in Fig. 2, the bridging board cannot betilted until the button has been swung to an angle of substantially 90from such position, whereupon it will release the bridging board fromthe bar B which the button engaged, and this endof...

the bridging board may then be lifted to tilt the top to the positionshown inFig. 1. 'It will be observed that each cap board B is providedwith a pair of bars D. These bars are connected with the cap boardbybolts'L. Whenthe table is to be transported or shipped from the factoryor dealer to place of destination, the bolts L can be removed andthelinks F, F disconnected by removing any one of the pivotpins f, f orf", whereupon the table top can be removed from the pedestal and cratedseparately for the purpose of such shipment. If desired, however, thenecessity of removing thebolts L may be avoided by employingthetype ofbinge shown in Figs. 8 and at, in which views a hinge leaf M,'connectedwith the bridging board, is provided with a hook shaped butt N, adaptedto loosely engage around a pintle 0, supported at its respective endsfrom the opposing leaf .M, the latter being attached to the bar D. \Viththis construction, the bar D may be so formed as to prevent, the hingemembers from disengaging, unless the bridging. board Cv is raised to asubstantially, vertical position. The links F, F will normally preventthe board from being lifted far enough to per mit a release of themember N, but when these links are disengaged, they can be raised toaycrtical position and removed.

We do not limit the scope of our invention to any specific form of hingeconnection, nor to any specific form of supporting member. \Ve prefer,however, to make the supporting members in the .form of separablepedestal members which include. cap plates substantially as illustrated,and guide bars between which the bridging boardswill be received when innormal position. ,By employing the guide bars and by recessingthebridging boards so as toreceive the guide barsin the recesses, it isobvious that we may relieve the hinges from all strain due to eitherlateral or longitudinal pres sures against the table, when the bridgingboards arein normal position. The'rewill thereforebe no pressure uponthe hinges, except whenth'e bridging boards are in'the raised or tiltedposition, as shown. The =structure'of the supporting member or base andthe structure of the bridging member or slide support with reference tothe question whether these parts are made in separable members or not,is therefore not esj-sential to our invention, since the slides areprimarily depended upon to permit a separation ofthe top boards and tosupport the top boardsin their various positions of ad'- ..vention .ispeculiarly adapted for use in an extension table having separablepedestal members or legs.
